Texas Sen. Ted Cruz ended his campaign for the Republican nomination Tuesday night, CBS News' Major Garrett has confirmed, effectively ensuring Donald Trump will become the GOP's standard-bearer in 2016.

"From the beginning, I've said that I would continue on as long as there was a viable path to victory," Cruz said. "Tonight, I'm sorry to say, it appears that path has been foreclosed. Together, we left it all on the field in Indiana. We gave it everything we've got. But the voters chose another path. And so with a heavy heart, but with boundless optimism for the long-term future of our nation, we are suspending our campaign.

Cruz conceded the race at an event in Indianapolis following the results of Tuesday's Indiana primary, which Trump won handily.

This pretty much nails on Fiorina-
Cruz's numbers went down in every poll (including Indiana) since he named her VP

So does Fiorina go down as worst VP candidate in history? Her candidate withdraws 6 days after being announced?! #IndianaPrimary#CruzBails
